TO ALL WHOM IT MAY CON CERN f -Be it known that EDWARD C LUrToN, deceased, late of Philadelphia, Pennsylvania, did invent an Improved Machine for Shearing Yarn; and I do Ahereby declare the following Ato be a full, clear, 'and .exact description of lthe same. i V I The invention of thesaid T. C. LUTToN- consists ot certain mechanism, fully described hereafter, for

shearing the protruding Vthreads from yarn, and thereby rendering the saine soft and smooth likev the yarn known as Berlin zephyr, as described in the patentgranted to the 'said E. T. C. LUTTON, on the 18th day of December',

In order to enable others skilled in the -art to make and use the invention, I will now proceed to describe itstcons'tructionand operation, reference being'l had to the accompanying drawing, which forms a par-t of4 this specification, and in which-P 'Figure 1 is .la side elevation of' theY improved machine for shearing yar'n.

V.Figure 2, section on the line 1;-2, iig. 1..` l V Figure 3, a section'ou-'the'line 3-4,"-g. 1.

Figures 4 and`,5de`tachedrvews of' part of'the machine drawn to an enlarged scale.

Figure 6, a section on the line 5 6, hg; 4; and

`Figure 7, a section onthe line 7 8, tig. 5. j

The frame of the machine consists of end-pieces, a a'aud a cross-piece, 6, andintoan opening, :e in each end-piece projectsthe leg d of the journal-box- B; set-screws ele e', which bear 'against the opposite sides and lower endpf this leg, maintaining the latter and its boxinA their `proper position vertically and laterally. In the boxes B B turn the journals of ashnft, C0n vwhich are a driving-pulley, f, and aA collar, y, and to the latter are secured a number of sharp-edged and inclined blades, 7L. in adjustable knife, D, isrsecured tothe front of the cross-piece b, in such a. position that as the shaft C revolves,- thc cutting-edges of the blades it pass in close l prokimityto the edge y of the knife, the latter being bevelled from the inside, asA seen iu'iigs. 6 and 7.

`To one edge of the bar Which forms the knife D is secured.l an adjustable plate or guide, E, one -edge of which is curved, as shown in the drawing, and on the straight edge of lthe guide is-a projection, on, which has 'a curved lower edge, y, and between which andthe face of the knife D is a narrow space, m,- the' upper edge of .the projection being parallel to and a short distance vbelow' lthe edge :al of the knife.

In the curved edge of the guide Eis 'a groove or channel, z', which is in lineiwith the space w, as shown in fig. 5, for a purpose described hereafter. i

To the opposite vertical edgeof the lknife D is secured an adjustable plate, F', a lug, n', at the upper end of which overlaps, but is not in Contact with the end ot' the projection m. l

To the l cross-piecehbetween the knife D and the eud-piece a, is secured an adjustable rod, F, from one side of which projects. a.pi n,a. 4

In an adjustable arm, G., secured to the cross-piece Z1, turns a short tube, H, to which is secured a grooved pulley, s, the inner end oi' the said tube being directly above the space w, as shown in iig. 2.

A driving-belt passing round the `pulleyf4 imparts to the shaft C a rotary motion in the direction of its arrow, and a rotarymotion in the direction ofrits arrow is imparted to the tube H by. a driving-'band passing round the grooved pulley s; 'lhe'yarn tebe sheared is passed round the rod F into the curved channel z' of the guide E, through' the space w beloar Athe projection n, to andrthrough the tube H, and to a suitable Windingbobbin,` the space 20 being just suicient in Width to allow` the yarn (which is temporarily twisted by the action of the revolving tube H) to pass freely between the projection m and the knife D,vtvl1ile the guide E and plate Ff, with its projection n, are so adjusted that the yarn shall be in close proximity to the edge xof the knife D, as shown in tig. 7. A, 1

As the yarn is twisted, theiibres projecting from it will extend above the edge of the knife D, and will be' sheared lcl-ose to the body of the yarn by the joint action of that knife and the revolving blades It, this shearing offthe yarn rendering it so smoothithat it resembles ine Bcrlirxvool, as fully described in the above-'mentioned patent'of the late E. VT. C. LUTT'ON. `This operation will continuo until' a. portion ofthe thread having a, knot in-it is bronghtngainst the guide E, when, es the spacelwis too ontiueted to admit vthe knot, the latter ,will

' -pass in contact with the lowei edgeof the pifojection m, {ig/. 4, thus 'withd-innnfing,` the Ayen'rom the cutting-eliges of the knives. The cutting of the knot, the consequent severingol the th1ead, and the interruption of thepiov cess of shearing, nre thus prevented. A'fter the knot has 4passed the projection m, the-yarn will resnme its formerl position in respect to the cutting-edges of the knives, by which it will be-sheared, Vis before..

As'the shaft C, knife D, guiilc' E, plate F', ioclF, und tube H, :we all afljvustnble, yarns oi` various sizes moy be-.uniformly guided, so as 'topass ini sneh closeproximity to .the knives.` thtlthe bi'es may be slieored close to the body-of the thread vWithout thelntter" being cut, while` the (knives. maybe `readily arljn'stell duringgthe operation of the machine, so as to obtain the best shearingellject.
